GY-30 BH1750FVI Digital Light Intensity Illumination Sensor Module

Direct Lux Output Telemetry: Incorporates a high-precision BH1750FVI IC that outputs digital light intensity directly in Lux (1 - 65535 lx), eliminating complex analog-to-digital calculations.

120° Broad Spectral Sensitivity: Features a wide spectral response that closely matches the visual sensitivity of the human eye for accurate ambient light evaluation.

Standard I²C Communication Interface: Communicates via a standard 2-wire I²C bus protocol with selectable slave address pins, enabling easy integration with microcontroller nodes.

High Ambient Light Rejection: Built-in digital noise filtering and infrared rejection minimize measurement interference from artificial or non-visible light sources.

Low Power Consumption: Operates on an efficient low-current architecture with an integrated power-down feature to conserve energy in battery-powered IoT nodes.

Housing & Board Material: Double-sided FR-4 glass-epoxy PCB with gold/tin-plated solder pads and surface-mount BH1750FVI IC.

Technical Specifications:

Input Supply Voltage: 3.0V - 5.0V DC (onboard 3.3V LDO regulator).

Measurement Range: 1 - 65535 lx (Lux).

Interface Bus: I²C Serial Interface (ADDR pin adjustable).

Product Weight: 0.05 kg.

Color: Blue PCB with Gold Contact Terminals.

Usage Advice: Connect VCC (3.3V-5V), GND, SCL, and SDA to your microcontroller I²C bus pins; set the ADDR pin high or low to select the target I²C address (0x23 or 0x5C).

Maintenance: Keep the optical sensing window free of dust, grease, or obstruction; clean gently with a dry lint-free microfiber cloth if dirty.

Essential Digital Ambient Light Transducer: Position as a core sensor module for smart home lighting automation, solar tracking arrays, display backlight control, and agricultural greenhouse monitoring.

Highlight Direct Lux Conversion: Emphasize how direct Lux digital reading simplifies firmware development compared to traditional photoresistors that require analog voltage conversion curves.

Recommended Cross-Sell Add-ons: Pair with GY-302 BH1750 light intensity module, OPT3001 Ambient Light Sensor, TEMT6000 Light Sensor Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
